more tower defence towers and mobs

add more towers the old ones are getting a bit lame.you should be able to send an enderdragon but it will cost 10000 coins.
add towers like missile towers,nuke towers,laser towers and stuff like that .and whats with the tower skin thing?

I want to be able to send an Enderdragon so bad...
This could make people spend more on air defences because 9/10 times people only asume we attack with a giant spamming Artillery Towers everywhere.
Yet they forget to build Archer Towers making a sweep with Blazes really easy.

I agree, however the Enderdragon is way too strong for this, don't you think?
They should add:
1. Ability for players to use towers.
2. Ability for players to control mobs they send.
3. Polar Tower, Sends out Polar bear mobs which attack enemies.
4. Guardian Tower, Sends out guardians:
At level One: Sends out 1 Guardian
At level Two: Sends out 2 Guardians
At level Three: Sends out 3 Guardians
Max level: Sends out an Elder Guardian
5. New Hostile Mobs:
Ender Man: If at low health, teleports a tower to the other team.
Shulker: When provoked too much by players, throws out a levitation particle which destroys blocks out of towers slowly.
I have more ideas, however I only wrote much due to my ideas not being accepted.
If anyone agrees then please reply!
